As an Authorized Cortec® Distributor, ECORR Systems provides corrosion-inhibiting oils, greases, hydraulic fluids, penetrating lubricants, metalworking lubricants, and oil additives. We can help select a product based on viscosity, speed, load, operating temperature, base-fluid compatibility, metal type, exposure conditions, and equipment requirements.

Lubrication with Added Corrosion Protection

Conventional lubricants are primarily selected to reduce friction, heat, and wear. However, machinery operating in humid, marine, industrial, or intermittently used environments may also need protection from condensation, salt, corrosive gases, and moisture contamination.

Selected Cortec® lubricants incorporate contact and Vapor phase Corrosion Inhibitor technology. Contact inhibitors protect surfaces reached by the lubricant, while VpCI® molecules can help protect compatible internal metal surfaces above the oil level or beyond direct lubricant contact.

Types of Cortec® Enhanced Lubricants

Industrial Gear Oils

Cortec® industrial gear oils provide lubrication and corrosion protection for compatible enclosed gears and gearboxes. The correct lubricant should be selected according to the equipment manufacturer’s viscosity grade, gear type, operating temperature, load, speed, seal materials, and existing lubricant.

Hydraulic Fluids

CorrLube™ hydraulic fluids are designed for compatible industrial, marine, construction, and mobile hydraulic systems. Selected formulations combine anti-wear and extreme-pressure performance with VpCI® corrosion protection for equipment operating in humid or environmentally sensitive areas.

Extreme-Pressure Greases

Lithium complex and other enhanced greases provide a persistent lubricating film for bearings, grease points, moving machinery, and components subjected to pressure, heat, water, or corrosive environments. Certain products can be used during both operation and equipment layup.

Penetrating Lubricants

Penetrating oils use low surface tension to work into rusted or tightly fitted assemblies. They can help loosen seized fasteners, displace moisture, lubricate moving surfaces, and leave behind corrosion-inhibiting protection.

Heavy-Duty Metalworking Lubricants

Cortec® offers multifunctional lubricant concentrates for demanding metalworking operations. Selected products provide lubrication and corrosion protection during compatible cutting, forming, machining, or processing applications.

Biobased Lubricants

Selected EcoLine® products use renewable seed-oil derivatives to provide lubrication and corrosion protection for bearings, chains, rollers, machinery, tools, and maintenance applications. Biobased content and biodegradability vary by formulation.

Lubricant and Oil Additives

Cortec® oil-soluble concentrates can add contact and vapor phase corrosion protection to compatible lubricating, hydraulic, circulating, or preservation oils. These concentrates require controlled dosing and compatibility testing before being introduced into an existing fluid.

How VpCI® Enhances Lubricant Protection

An ordinary oil or grease protects the surfaces it directly covers. In partially filled gearboxes, hydraulic reservoirs, oil sumps, and enclosed equipment, some internal surfaces may remain above the lubricant level and exposed to humid air or condensation.

Selected Cortec® lubricants and oil additives release VpCI® molecules into the enclosed atmosphere. These molecules migrate to accessible metal surfaces and supplement the protection provided by the lubricant’s direct-contact film.

Lubricants for Operation and Layup

Machinery may corrode during operation, but the risk often increases during shutdown when equipment cools and moisture condenses internally. Seasonal equipment, standby systems, stored machinery, and spare gearboxes may remain idle long enough for corrosion to develop on gears, bearings, housings, and internal surfaces.

Selected Cortec® lubricants can support both normal operation and equipment layup. Product suitability should be confirmed before using a preservation lubricant as an operating fluid or leaving it in place when machinery returns to service.

Choosing Oil Versus Grease

Oil is generally used where the lubricant must circulate, transfer heat, flow through passages, or continuously reach moving surfaces. Common applications include gearboxes, hydraulic systems, turbines, compressors, and circulating lubrication systems.

Grease is typically used where a lubricant must remain at a specific point, resist leakage, seal out contaminants, or support slower-moving and heavily loaded components. Bearings, hinges, bushings, open mechanisms, and centralized grease systems are common examples.

Selecting the Correct Viscosity

Viscosity describes a lubricant’s resistance to flow. A lubricant that is too thin may not maintain an adequate film under load, while one that is too thick may increase drag, generate heat, restrict circulation, or prevent proper cold-weather operation.

Always use the viscosity grade required by the equipment manufacturer unless an approved engineering evaluation supports a change. Operating temperature, load, speed, startup conditions, pumpability, and lubricant delivery method must also be considered.

Selecting the Correct Grease

Grease selection should consider the required NLGI grade, base-oil viscosity, thickener type, operating temperature, load, speed, water exposure, corrosion environment, relubrication interval, and compatibility with the grease already in the equipment.

Mixing incompatible greases can cause softening, hardening, oil separation, loss of mechanical stability, or reduced lubrication performance. Existing grease may need to be removed before changing products.

Benefits of Cortec® Enhanced Lubricants

• Reduce friction and mechanical wear
• Provide contact corrosion protection on lubricated surfaces
• Protect selected enclosed surfaces through VpCI® action
• Support equipment operation, shutdown, storage, and layup
• Offer products for gears, hydraulics, bearings, chains, and metalworking
• Provide options for humid, marine, and corrosive environments
• Include selected biobased and environmentally responsible formulations
• Help extend component and equipment service life

Lubricant Compatibility

A lubricant should not be selected solely because it provides corrosion protection. It must also meet the mechanical, viscosity, temperature, seal, filtration, and equipment requirements of the application.

Before changing lubricants or adding a concentrate, evaluate compatibility with:

• The existing base oil and additive package
• Seals, gaskets, hoses, and elastomers
• Painted and coated internal surfaces
• Filters and moisture-separation systems
• Metals and alloys within the equipment
• Equipment manufacturer specifications

Finished Lubricants Versus Additives

A finished lubricant is supplied with its base fluid and performance additives already formulated for a defined use. A lubricant additive is a concentrate intended to modify a compatible oil at a specified treatment level.

Concentrated additives should not be used as stand-alone lubricants unless the technical documentation specifically permits it. Adding an aftermarket product to an existing oil may also affect viscosity, wear protection, demulsibility, filtration, oxidation resistance, or equipment warranty requirements.

Food Machinery Lubrication

Lubricants used in food-processing facilities should be selected according to the location and likelihood of food contact. NSF H1 registration generally applies to lubricants used where incidental food contact is possible, while other categories apply to different uses.

“Food grade” does not mean edible or suitable for intentional food contact. Confirm the current registration, category, formulation, facility requirements, and approved use before application.

Biobased and Biodegradable Lubricants

Selected Cortec® lubricants incorporate renewable biological ingredients or are formulated for biodegradability. These characteristics may support environmentally sensitive operations, but they do not replace the need to evaluate load, temperature, oxidation stability, water resistance, and equipment compatibility.

Used lubricant may contain metals, process chemicals, fuel, dirt, or other contaminants and must be collected and disposed of according to facility procedures and applicable regulations.
